Question

как рассчитать малекулярную массу веществ H3PO4CuCl2H3PO4Ca(OH)2Al2(SO4)3CH3COOH

Answer 1

M (H3PO4) = 3 + 31 + 64 = 98 
M (CuCL2) = 63 + (35 X 2) = 133
M (H3PO4) = 3 + 31 + 64 = 98
M (Ca(OH)2) = 40+ (16+3) X 2 = 118
M (Al2(SO4)3) = (27 X 2) + (32+64) x 3 = 450
M (CH3COOH) = 12+3+12+32+1=60
